He is a Mercedes mechanic... He said the are ecu errors no communication
Customer reply replied 2 years ago
But the new ecu no response
Customer reply replied 2 years ago
He did the same thing you are saying... There is just communication error .. The Ecu not communicating to the car
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

You keep telling me the same thing over and over. And don't say ECU. That means nothing. Our modules have specific names. Are you telling me the SCANNER cannot communicate with the car ? Or just the engine computer ?

Engine computer

Front left black box
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Ok. Here's what I need the quick test printout for ...... Let me explain

Ask Your Own Mercedes Question
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

There are 5 modules or more on the communication system ,

Ask Your Own Mercedes Question
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

If 4 of the modules have fault codes that all say "cannot communicate with engine computer " then most likely the engine computer is bad. If the scanner cannot talk to any module on the communication lines means that one module is failing and killing the communication. So without the printout I cannot tell or advise on what to check. But once I get the printout I know I can help you.

The scanner won't communicate with the Ecu when the car dies.... No communication at all..
Customer reply replied 2 years ago
When the car finally wants to start again the star system
Only gets communication error with ecu
Customer reply replied 2 years ago
why with the new ecu the same issue... Turn the key no crank and only hear the fan
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Ok , just you explaining to me still does not help. Is there a issue with getting me the printout ? If there is then I will have to let another expert try to help , please believe me I can help but I need To SEE the fault codes. I cannot tell you why about anything. You must understand
